How to Select Current Rating (Engineering Selection Guide)
The selection of current rating in temporary power distribution systems is determined by load type, power source stability, cable cross-section, and the number of downstream circuits. Each current range defines the system’s internal busbar capacity, protection coordination level (MCB/MCCB + RCD), and socket output configuration (16A / 32A / 63A IEC60309 interfaces).
| Current Range | Typical Power Source | Load Characteristics | Application Environment | System Structure Behavior | Typical Output Configuration |
|---|---|---|---|---|---|
| 16A – 32A | Single-phase supply / small generator | Low load, intermittent usage, portable equipment | Maintenance work, small workshops, temporary lighting setups | Single incoming circuit distributes power directly through MCB protection; minimal branching; short cable runs | 16A / 32A IEC60309 sockets, single-layer distribution |
| 63A – 125A | Three-phase generator or site distribution panel | Medium to high mixed load with simultaneous equipment operation | Construction sites, outdoor events, temporary stage systems | Multi-branch distribution via internal copper busbar; coordinated protection between MCB/MCCB and RCD modules; supports parallel load transfer | 16A / 32A / 63A mixed socket configuration with segmented protection zones |
| 250A – 800A | Industrial transformer / high-capacity generator | High continuous load, multi-system operation, heavy machinery clusters | Shipyards, mining operations, tunnel engineering, industrial plant shutdown power | Main MCCB inlet feeds high-capacity copper busbar system; multi-layer sub-distribution with fault isolation between zones; designed for long-duration load transfer | Multiple 63A industrial outputs + feeder terminals for sub-distribution panels |
